Abstract
A broadband stacked microstrip antenna with cavity-backed ground plat is presented in this paper, where the proximity-coupling feeding mechanism is employed. Also, there is a slot on the surface of the lower patch in this antenna. With the slot, the coupling to the top patch will be increased, and the defect that the antiphase of the currents on the stacked patches will be improved in a certain extent. And due to the interaction between the cavity and the lower patch, a very larger bandwidth is achieved. The simulated results shows the impedance bandwidth is 107% (VSWR<2). At last, the simulated radiation patterns and gain of the antenna are presented.
